I'll be getting to the UK mid to late July...would this be too late to catch summer school work? I can apply now, but do summer schools take teachers for late July and August? Would I be better off scouting around for year round work once I'm there in July?

I'm considering London, but what other cities would be good for ESL teaching? I also have to consider my partner who is a Chemical Engineer, so I assume the south coast would be out? Any ideas are really appreciated.
